It will be apparent that the described embodiments are some, but not all, embodiments of the utility model. All other embodiments, which are obtained by a person skilled in the art based on the described embodiments of the utility model, fall within the scope of protection of the utility model.

The terms "first," "second," and the like, as used herein, do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. The terms "connected" or "connected," and the like, are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

A rotation measurement target for total station laser beam control steering according to an embodiment of the present utility model will be described in detail with reference to the accompanying drawings.
A rotation measurement target for total station laser beam controlled steering according to an embodiment of the present utility model, as shown in fig. 1, may include: a base 1, a drive shaft 2, a measurement target 3, a plurality of azimuth sensors 4, and a controller (not shown).
Wherein the bottom end of the transmission shaft 2 is arranged on the base 1.
The measuring target 3 is installed on the top of the transmission shaft 2, and the transmission shaft 2 drives the measuring target 3 to rotate by taking the transmission shaft 2 as a rotating shaft.
A plurality of azimuth sensors 4 are installed at a side of the base 1 at intervals along the circumferential direction of the base 1, the azimuth sensors 4 being for detecting the direction of irradiation of an incident laser beam and emitting an azimuth signal.
The controller is arranged in the base 1 and is used for receiving the azimuth signal sent by the azimuth sensor 4 and controlling the transmission shaft 2 to drive the measuring target 3 to rotate to the designated azimuth according to the azimuth signal.
Specifically, according to the rotation measuring target for controlling steering of the total station laser beam in the embodiment of the utility model, the direction of irradiation of the incident laser beam is detected by the direction sensor 4 arranged on the side surface of the base 1, then the direction sensor 4 corresponding to the detection of the incident laser beam sends a direction signal to the controller arranged in the base 1, and the controller controls the transmission shaft 2 to rotate to drive the measuring target 3 at the top of the transmission shaft to rotate towards the designated direction, so that the measuring target 3 can automatically steer to meet the viewing requirement, and the cost is low.
For example, when one of the orientation sensors 4 detects the laser beam irradiated thereto, it generates a detection signal, and the other orientation sensors 4 do not generate any detection signal since they do not detect the corresponding laser beam, whereby the orientation can be determined according to the position of the specific orientation sensor generating the detection signal, that is, the "detection signal" corresponds to the orientation at the same time, that is, it is an orientation signal.
After the azimuth sensor 4 sends out an azimuth signal, the controller only needs to control the transmission shaft 2 to rotate and drive the target 3 to reach the corresponding azimuth sensor 4. The specific manner in which the controller controls the rotation of the propeller shaft 2 is not limited, and may be controlled by a circuit configuration or a program, for example. As an example of the circuit configuration, for example, after the azimuth sensor 4 generates a detection signal, the controller closes the circuit and starts to operate due to the detection signal, drives the transmission shaft 2 to rotate, and when the position of the azimuth sensor 4 is reached, the controller is triggered to stop operating, that is, the transmission shaft 2 is not rotated any more by the detection signal. These functions can be easily realized based on the conventional circuit technology, and a detailed description thereof will be omitted here.
In some embodiments, the rotation measuring target for controlling steering of the total station laser beam may further include a driving motor (not shown), the base 1 is cylindrical and hollow, the driving motor is installed inside the base 1, the bottom end of the transmission shaft 2 is connected to the driving motor by the surface of the base 1 and extending into the base 1, and the controller controls the driving motor to drive the transmission shaft 2 to rotate.
That is, a driving motor is arranged in the base 1, an output end of the driving motor is connected with an input end of the transmission shaft 2, and the driving motor is controlled by the controller to drive the transmission shaft 2 to rotate, so that the control is simple and reliable.
In some embodiments, as shown in fig. 1 and 2, the measurement target 3 is planar, and the transmission shaft 2 is disposed below the measurement target 3 along the radial direction of the measurement target 3.
Thereby, the measuring target 3 can be stably and reliably vertically mounted on the drive shaft 2, and observation and aiming measurement are facilitated.
In some embodiments, as shown in fig. 1, the center of the measurement target 3 is provided with a bulls-eye, which coincides with the axis of the transmission shaft 2.
Therefore, the target can ensure that the space position of the target is unchanged when the target rotates along with the measuring target 3, and the target can be conveniently and accurately aligned with the position during measurement when the target is used for aiming a measuring instrument, so that the measuring precision is improved. In addition, the measuring target 3 may be formed by sticking a highly reflective reflecting sheet with a cross-shaped target center on a planar structure, or may be provided with a commercially available reflecting prism for measuring a finished product as a target, as long as the center of the target coincides with the axis of the transmission shaft.
